A Hamilton-area man wanted in connection with a pair of 2017 targeted homicides in Vaughan and Waterdown, Ont., has been arrested in Mexico, police have confirmed.
York Regional Police confirmed to Global News that Daniel Tomassetti was in custody. The police service says it’s conducting a joint investigation with Hamilton police into the cases.
“He is being detained and an extradition order is being sought,” a spokesperson for York Regional Police wrote in an email.
Hamilton Police said in an email to Global News that Tomassetti is “contesting extradition back to Canada.”
Hamilton police confirmed to Global News that Tomassetti was arrested in August 2025.
Tomassetti, of Ancaster, Ont., was previously listed on Canada’s most wanted list on the BOLO program as number 21 of 25 high-risk suspects being sought by police.
Tomassetti is wanted in connection with the fatal shooting of Mila Barberi on Caster Avenue near Highway 7 in late March of 2017.

He is also wanted in the attempted murder of Saverio Serrano, Barberi’s boyfriend.
In 2023, Barberi’s family renewed their calls for help in capturing the man police accuse of playing a role in their daughter’s murder.
Barberi was shot in a parking lot on March 14, 2017, one week after her 28th birthday, when picking up Serrano from work.
Tomassetti is also wanted for the high-profile murder of notorious mobster Angelo Musitano.
Musitano, then 39, was shot dead in his truck after pulling into the driveway of his home in Waterdown with his wife and children at home.
Tomassetti is facing two counts of first-degree murder, a charge of attempted murder, and three counts of conspiracy to commit murder.
“The Barberi family, this is something that is still ongoing for them and always will for the rest of their lives, and there’s one person that’s still outstanding that was involved in their daughter’s murder,” Hamilton police Det. Sgt. Jason Cattle said in 2023.
According to police, Tomassetti flew to Cancun, Mexico in January 2018, leaving a trail of pain, confusion and fear behind as several police units try to piece together what happened.
Criminal defence lawyer Jeff Hershberg, who is not involved in the case, said he’s not surprised Tomassetti is fighting extradition. He did say it is a difficult process to fight.
Under the Extradition Act, a person can be extradited if the alleged crime is also recognized as criminal by the second country.
“Essentially the requesting state, which is Canada, simply just has to provide sufficient evidence to justify the arrest and his committal under the Mexican law,” Hershberg said. “They’re going to have to show a valid arrest warrant, which they’ll be able to do and any supporting documents. The test itself, though, is quite low.”
Hershberg noted Canada does not have to prove guilt beyond a reasonable doubt, just that there is evidence “supporting the inference of guilty.”
Tomassetti had no criminal record. He lived in Ancaster, where he operated a travel company and worked in fitness.
